On the Draftsight Free Trial page, there’s currently a notice telling users that they have discontinued the free version.

It has some important consequences that you might want to consider if you’re already a Draftsight user:

If you have a version older than Draftsight 2019 you probably shouldn’t download the new version. Because Dassault Systèmes say that if you download the new version you will only get a 30 day free trial and thereafter you’ll need to pay.

All free versions of Draftsight will stop working after December 31, 2019. If you want to continue using Draftsight after that date you would need to purchase a Draftisght license.

Therefore the only way to legitimately use Draftsight for free is their 30-day free trial.
